What you need to know about remote laser welding

The utilization of remote laser welding technology that can provide much faster positioning speeds and its application to the manufacturing processes are discussed. There are certain design considerations that welding engineers need to be aware of for proper design of parts and assemblies that are going to be remote laser welded. The key technology behind remote laser welding is using a scan head to rapidly position and focus the laser beam on the work surface. Laser welding should be done normal to the work surface because the weld profile will take on the same angle that the laser beam has with the normal to the work surface. Process development should be done for each family of parts that is going to be manufactured as there is a great deal of flexibility in the remote laser welding process. The advantages along with the added benefits of the remote welding process should help the automotive market reduce cost and increase production, if it is applied properly.
